This research is about the cultural marks and meanings production on the popular culture context, in honor of Catholics Saints of June: Saint Antony; Saint John and Saint Peter (with celebrations in June 13th, 24th and 30th respectively). These marks are find on the newspapers’ photography of Tribuna do Norte (Natal, Rio Grande do Norte, Brazil) and Correio da Manhã (Lisbon, Portugal). All the photos were published in June 2012. The analysis has theory and methodology in Folkcommunication and in Sociocultural Photocatography. The investigation has focus in the meanings of these marks on the photojournalism about the popular parties and their practices. The study observes also a common view to report about popular culture, which has the influence of a hegemonic paradigm that considers itself the only true one.

In this work, we investigate the symbolic construction of a particular spatiality, starting from the theoretical assumption that spaces are subjective constructions guided by different cultures, feelings and rationales, but mostly spaces are human constructs driven by social relations, as a result of the material investment and symbol that reflects the needs of a particular society at a given time of historical development. Accordingly, we analyze the construction and symbolic imagery of the central region of Portugal, the Alentejo, from the literary production (1916 – 1930) the English poet Florbela Espanca D'Alma Conception Espanca. Thus, we propose to analyze the florbelian work not only from its internal relations, but also external, emphasizing the link between history, space and literature. Thus, we propose to inquire about the symbolic dimension – the meanings of images and representations – which prompted one of the most controversial Portuguese poets of the early twentieth to look into the poetic construction of space Alentejo century, questioning not only the senses brokered by speech literary Florbela Espanca to invent your Alentejo, adorned with memories, pain and longing, but investigate how the socio-cultural environment influenced your work, in your life and ways to feel and live the Alentejo. To better understand how the poet means the Alentejo spatiality, throughout this work we question three categories of space in the work of Florbela Espanca: the region, the countryside and the landscape of the Alentejo. Thus, this research falls within the field of cultural history in the medical we will work with the entire literary output Florbela Espanca, letters, diaries, photos and biographical and literary criticism, by establishing the time frame of 1916 – beginning of intellectual activity Florbela Spank – the 1930 – publication of Blossom Heath (posthumous) and the suicide of the poet. Therefore, a constant symbolic exercise of words crossed by more subjective feelings of the subject, all the time our work will be guided by the question of what would be the Alentejo for the poet, who senses and meanings across this spatiality that marked so sovereignly happiest memories and sad life Florbela Espanca.

The search for new meanings in the basic education teaching-learning process has caused the development of public policies for mother language teaching, such as the Portuguese Language Olympics (OLP). To contribute to this search, this intervention project has as object of study reading and writing practices developed in the OLP through the educational model arising from literacy projects (TINOCO, 2008). In working towards, the general aim of reframing reading and writing practices through the PLO, developed from the teaching model that comes of literacy projects, we established three specific objectives: a) reflect on a national writing contest; b) to realign conceptual and methodological the Portuguese classes of the 7th grade school due to the developed project; c) to improve the reading and writing practices of the students in 7th grade of school where we operate. Therefore, we base ourselves in the history of Portuguese teaching in Brazil (SOARES, 2002; GERALDI, 2008), the dialogical conception of language (BAKHTIN, VOLOCHÍNOV [1929] 2009; SOARES, 1998; FARACO, 2009) in Literacy Studies (KLEIMAN, 2001, 2005, 2006; TINOCO, 2008; OLIVEIRA; TINOCO; SANTOS, 2011; STREET, 2014), the learning community concept (AFONSO, 2001), in studies of retextualization (OLIVEIRA, 2005; MARCUSCHI, 2010), gender discursive literary memories (CLARA; ALTENFELDER; ALMEIDA, 20--), in written evidence (POSSENTI, 2002) and Textual Linguistics (MARCUSCHI, 2008; ANTUNES, 2009; KOCH, 2011; SILVA [et. al.], 2013). Methodologically, this qualitative research (LÜDKE; ANDRÉ, 1986; ANDRÉ, 2005) is anchored in Applied Linguistics (MOITA LOPES, 1996). This research was supporting by students in the 7th grade, teachers, management team and parents, as well as people outside of school community. The instruments used for the generation of data were semi-structured interview, students‟ texts, audio recordings and video, photos, OLP material (teacher's book, a collection of texts and CD-ROM). The data generated allowed us to establish the following categories of analysis in relation to the texts produced: authorship, in formativeness, discursive progression, compositional structure, content, style, and language aspects. In addition, throughout the project, the collaborators have produced texts of various genres: oral interview and written request letter, legal, literary memories, oral and experience report. Also experienced a local award and participated in a national competition. They produced a video and a book with stories and student authorship of illustrations. The results achieved show that the literacy project developed also allowed macro changes: reading and writing practices, once considered strictly school studied, they were transformed into broader social practices, through which various literacy agents were able to collaboratively act. In short, they experienced writing practices that go beyond the classroom and the teacher-student relationship.

A large series of laboratory ice crushing experiments was performed to investigate the effects of external boundary condition and indenter contact geometry on ice load magnitude under crushing conditions. Four boundary conditions were considered: dry cases, submerged cases, and cases with the presence of snow and granular ice material on the indenter surface. Indenter geometries were a flat plate, wedge shaped indenter, (reverse) conical indenter, and spherical indenter. These were impacted with artificially produced ice specimens of conical shape with 20° and 30° cone angles. All indenter – ice combinations were tested in dry and submerged environments at 1 mm/s and 100 mm/s indentation rates. Additional tests with the flat indentation plate were conducted at 10 mm/s impact velocity and a subset of scenarios with snow and granular ice material was evaluated. The tests were performed using a material testing system (MTS) machine located inside a cold room at an ambient temperature of - 7°C. Data acquisition comprised time, vertical force, and displacement. In several tests with the flat plate and wedge shaped indenter, supplementary information on local pressure patterns and contact area were obtained using tactile pressure sensors. All tests were recorded with a high speed video camera and still photos were taken before and after each test. Thin sections were taken of some specimens as well. Ice loads were found to strongly depend on contact condition, interrelated with pre-existing confinement and indentation rate. Submergence yielded higher forces, especially at the high indentation rate. This was very evident for the flat indentation plate and spherical indenter, and with restrictions for the wedge shaped indenter. No indication was found for the conical indenter. For the conical indenter it was concluded that the structural restriction due to the indenter geometry was dominating. The working surface for the water to act was not sufficient to influence the failure processes and associated ice loads. The presence of snow and granular ice significantly increased the forces at the low indentation rate (with the flat indentation plate) that were higher compared to submerged cases and far above the dry contact condition. Contact area measurements revealed a correlation of higher forces with a concurrent increase in actual contact area that depended on the respective boundary condition. In submergence, ice debris constitution was changed; ice extrusion, as well as crack development and propagation were impeded. Snow and granular ice seemed to provide additional material sources for establishing larger contact areas. The dry contact condition generally had the smallest real contact area, as well as the lowest forces. The comparison of nominal and measured contact areas revealed distinct deviations. The incorporation of those differences in contact process pressures-area relationships indicated that the overall process pressure was not substantially affected by the increased loads.

From the 12th until the 17th of July 2016, research vessel Maria S. Merian entered the Nordvestfjord of Scorsby Sound (East Greenland) as part of research cruise MSM56, "Ecological chemistry in Arctic fjords". A large variety of chemical and biological parameters of fjord and meltwater were measured during this cruise to characterize biogeochemical fluxes in arctic fjords. The photo documentation described here was a side project. It was started when we were close to the Daugaard-Jensen glacier at the end of the Nordvestfjord and realized that not many people have seen this area before and photos available for scientists are probably rare. These pictures shall help to document climate and landscape changes in a remote area of East Greenland. Pictures were taken with a Panasonic Lumix G6 equipped with either a 14-42 or 45-150 objective (zoom factor available in jpg metadata). Polarizer filters were used on both objectives. The time between taking the pictures and writing down the coordinates was maximally one minute but usually shorter. The uncertainty in position is therefore small as we were steaming slowly most of the time the pictures were taken (i.e. below 5 knots). I assume the uncertainty is in most cases below 200 m radius of the noted position. I did not check the direction I directed the camera to with a compass at the beginning. Hence, the direction that was noted is an approximation based on the navigation map and the positioning of the ship. The uncertainty was probably around +/- 40° but initially (pictures 1-17) perhaps even higher as this documentation was a spontaneous idea and it took some time to get the orientation right. It should be easy, however, to find the location of the mountains and glaciers when being on the respective positions because the mountains have a quite characteristic shape. In a later stage of this documentation, I took pictures from the bridge and used the gyros to approximate the direction the camera was pointed at. Here the uncertainty was much lower (i.e. +/- 20° or better). Directions approximated with the help of gyros have degree values in the overview table. The ship data provided in the MSM56 cruise report will contain all kinds of sensor data from Maria S. Merian sensor setup. This data can also be used to further constrain the position the pictures were taken because the exact time a photo was shot is noted in the metadata of the .jpg photo file. The shipboard clock was set on UTC. It was 57 minutes and 45 seconds behind the time in the camera. For example 12:57:45 on the camera was 12:00:00 UTC on the ship. All pictures provided here can be used for scientific purposes. In case of usage in presentations etc. please acknowledge RV Maria S. Merian (MSM56) and Lennart T. Bach as author. Please inform me and ask for reprint permission in case you want to use the pictures for scientific publications. I would like to thank all participants and the crew of Maria S. Merian Cruise 56 (MSM56, Ecological chemistry in Arctic fjords).

Underwater georeferenced photo-transect surveys were conducted on December 10-15, 2011 at various sections of the reef at Lizard Island, Great Barrier Reef. For this survey a snorkeler or diver swam over the bottom while taking photos of the benthos at a set height using a standard digital camera and towing a GPS in a surface float which logged the track every five seconds. A standard digital compact camera was placed in an underwater housing and fitted with a 16 mm lens which provided a 1.0 m x 1.0 m footprint, at 0.5 m height above the benthos. Horizontal distance between photos was estimated by three fin kicks of the survey diver/snorkeler, which corresponded to a surface distance of approximately 2.0 - 4.0 m. The GPS was placed in a dry-bag and logged the position as it floated at the surface while being towed by the photographer. A total of 5,735 benthic photos were taken. A floating GPS setup connected to the swimmer/diver by a line enabled recording of coordinates of each benthic photo (Roelfsema 2009). Approximation of coordinates of each benthic photo was conducted based on the photo timestamp and GPS coordinate time stamp, using GPS Photo Link Software (www.geospatialexperts.com). Coordinates of each photo were interpolated by finding the GPS coordinates that were logged at a set time before and after the photo was captured. Benthic or substrate cover data was derived from each photo by randomly placing 24 points over each image using the Coral Point Count for Microsoft Excel program (Kohler and Gill, 2006). Each point was then assigned to 1 of 78 cover types, which represented the benthic feature beneath it. Benthic cover composition summary of each photo scores was generated automatically using CPCE program. The resulting benthic cover data of each photo was linked to GPS coordinates, saved as an ArcMap point shapefile, and projected to Universal Transverse Mercator WGS84 Zone 55 South.

Underwater georeferenced photo-transect surveys were conducted on October 3-7, 2012 at various sections of the reef and lagoon at Lizard Island, Great Barrier Reef. For this survey a snorkeler swam while taking photos of the benthos at a set distance from the benthos using a standard digital camera and towing a GPS in a surface float which logged the track every five seconds. A Canon G12 digital camera was placed in a Canon underwater housing and photos were taken at 1 m height above the benthos. Horizontal distance between photos was estimated by three fin kicks of the survey snorkeler, which corresponded to a surface distance of approximately 2.0 - 4.0 m. The GPS was placed in a dry bag and logged the position at the surface while being towed by the photographer (Roelfsema, 2009). A total of 1,265 benthic photos were taken. Approximation of coordinates of each benthic photo was conducted based on the photo timestamp and GPS coordinate time stamp, using GPS Photo Link Software (www.geospatialexperts.com). Coordinates of each photo were interpolated by finding the GPS coordinates that were logged at a set time before and after the photo was captured.
